POLYSTYRENE CRYSTAL 1960N is a high heat resistance crystal polystyrene with very high flow for the production of thick insulation board. The very low viscosity of this grade combined with its high heat resistance makes it particularly suitable for the production of insulation board with gases such as CO2 and HFC. This grade is not lubricated. |
